Filed: 1956-12-07
Abstract: 836,613. Smoke indicating apparatus. GENERAL ELECTRIC CO. Ltd. Dec. 9, 1957 [Dec. 7, 1956], No. 37523/56. Class 40 (3). Smoke indicating apparatus of the type comprising photo-cell and relay circuit wherein the ambiguity introduced by the large difference between the energizing and de-energizing currents of the relay is overcome, hence decreasing the amount by which the smoke density must fall before this fall is indicated. Light from the lamp 1 is directed across a chimney or like installation to illuminate the cell 2 connected in the grid circuit of the pentode valve 3. A decrease in light falling on the cell increases the current through the valve and at a predetermined smoke density level relay 5 operates, energizing the alarm 9 via relay 8. After a delay determined by the delay circuit 18, switch 20 operates momentarily opening the contacts 23 in the circuit relay 5. If the smoke density has not decreased below the predetermined level the valve current will remake relay 5. The check process continues until the smoke density falls below the predetermined level when the valve current is insufficient to make relay 5. After a time delay controlled by condenser 24, which prevents switching off the alarm during the check process, the relay 8 releases switching-off the alarm 9.

Title: Automatic vehicle identification
IPC: B61L25/04
Filed: 1971-08-13
Abstract: 1330377 Vehicle identification COMPUTER IDENTICS CORP 13 Aug 1971 [26 Aug 1970] 38117/71 Heading G4H In a system for optically scanning a code plate comprising a plurality of bands of red, blue, white or black, wherein the plate comprises a plurality of stripes each having a first band of white, red or blue and a second band of these colours or of black, each stripe being separated from the next by a black band, means are provided for deriving a signal indicative of the relative width of the stripe and the following black space in order to prevent the reading of spurious information relating to a second colour band in the stripe, if such is absent. In a preferred embodiment, the code plates are mounted on railway wagons and are scanned vertically as the wagons move past, suitable sensors for red and blue light being provided, both responding to white, and neither to black bands or spaces. Upon scanning a stripe, suitable signals R, B are derived from the sensors not shown and by using delay circuits and OR gates, the signals 42-52 are derived at 40 as shown. Using at 54 an array of AND gates in combination with trigger circuits responsive to pulse edges the first occurring colour signal is sampled by the leading edge of the slightly delayed Red or Blue R + B DELAY signal and the information on one of lines 56-62 used to "set" one of four shift registers, not shown, at 64. Similarly the second band signal of the stripe is slightly delayed and sampled by the trailing edge of the non-delayed red or blue signal R + B. The leading edge of the R+B signal of the next stripe causes read-out over line 88 of the shift registers and a 4-bit word 68-72 indicative of the previous stripe is read-in at 38. The red or blue signal R+B is also applied to a counter 78 to cause the latter to count up clock pulses during the time the signal is present, and when it is removed during passage of a black band or space, the counter counts down. The shift signal on line 88 causes counter 78 to reset to zero and also interrogates the polarity of the count at that instant whereby if this is positive indicating that the R + B signal is wider than the next black space, i.e. the second band is coloured, causes a signal from encoder 79 to enable AND gates 84, 86 to read in information relating to both bands of the stripe to store 38, whereas if the count is negative, any signal on lines 70, 72 is erroneous, the second band being black, and gates 84, 86 are not enabled. Upon scanning of the penultimate stripe of the plate which is coded as a STOP signal, logic at 80 causes the counting action at 78 to be inverted and the response of the encoder 79 correspondingly changed to allow comparison of the next space with the last, parity stripe to be made.

Abstract: 1, 015, 916. Stabilizing line of sight. FERRANTI Ltd. Oct. 10, 1963 [Oct. 12, 1962], No. 38646/62. Heading G2J. An optical instrument for stabilizing in a picture frame area of the instrument an image of an external object against small rotational movements of the instrument, includes a gyro mounted mirror. Thus where the camera is mounted in a guided missile for transmitting a television picture to an aircraft, the received picture will not 'dance' about the screen as a result of roll or pitch of the missile. The invention is also suitable for use with hand held movie and television cameras used e.g. for sporting events. The instrument comprises a window 24, a pair of constant deviation mirrors 25, a composite lens 17, a two gimbal gyro 12 carrying a plane, concave or convex mirror 15, a picture frame area 20 and a t.v. camera 21. Preferably, the length of the optical path 22 is half the focal length of lens system 17. Various modifications are described, including replacing the mirrors 25 with a prism, employing constant deviation mirror systems in each optical path, aligning the spin axis with the line of sight and mounting the stabilized mirror at an angle thereto, and by utilising semi reflecting mirrors. The camera may be mounted outside casing 10, and connected to the light system by a bundle of optical fibres. Where the invention is applied to trolley mounted t.v. cameras, the gyro is partially restrained by passing currents through range and deflection coils; thus any sustained angular movement of the casing causes a restoring couple to be applied to the gyro, thereby causing it to follow any sustained movement smoothly.

Abstract: 1,137,448. Microphone circuits; automatic volume control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 Aug., 1967, No. 38994/67. Headings H4J and H4R. In an audio amplifier system of the fixed frequency pilot tone A.G.C. type the fixed frequency tone is of ultrasonic frequency and is injected acoustically. The system is for use with an ultrasonic pilot tone generator and transducer carried by a performer, e.g. on a lapel, spectacles, tie-pin or hung round the neck. By such arrangement movements of the performer, which cause variations in input volume, cause little variation in output volume. A loud-speaker S (Fig. 1) is fed by an amplifier A which amplifies both audio signals and ultrasonic pilot signals. A filter F separates the pilot signals which are utilized to provide A.G.C. (e.g. by rectification) to control the amplifier gain. A single microphone M receives both sound and ultrasonic waves. The sound source P of the performer has polar diagram p and the pilot transducer T has a polar diagram t. The transducer T is more directional than the performer but this does not matter at low ultrasonic frequencies (e.g. 20 to 25 kc/s.) if major movements are relied upon. With a higher ultrasonic frequency the polar diagram t may be widened, e.g. by using two or more transducers in parallel. Alternatively a microphone (M1), Fig. 2 (not shown) receives sound waves while a microphone (M2) receives the ultrasonic waves, the outputs from the microphones (M1, M2) being applied to the amplifier (A) by a mixer (C1). In another arrangement the ultrasonic microphone (M2), Fig. 3 (not shown) is coupled directly to the A.G.C. device which controls the amplifier (A), there being no feed-back type A.G.C. loop.
